WARNING: Always start with lower doses due to differences between individual body weight, tolerance, metabolism, and personal sensitivity. See responsible use section.

Haloperidol (trade name Haldol) is an antipsychotic drug used to treat a variety of mental disorders, such as schizophrenia, mania, bipolar disorder, delirium, psychosis, Tourette syndrome, as well as other symptoms. It was first synthesized in 1958 by Paul Janssen[1] from meperidine[2]. Haloperidol is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.[3] It is also one of the most frequently prescribed typical antipsychotics and is sometimes carried by medical services as an emergency sedative.
As a typical antipsychotic, haloperidol has a diverse pharmacological profile. Primarily, haloperidol acts on dopamine D2receptors as an antagonist, as well as a D3 inverse agonist. Haloperidol is also an antagonist of the 5-HT2A receptor, although this effect is not as powerful as that of quetiapine. Unlike many antipsychotcs, haloperidol has negligible affinity for the muscarinic acetylcholine receptors as well as the histamine receptors, which results in less sedation, weight gain and hypotension.[4]
Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWikicontributors. As a result, they should be viewed with a healthy degree of skepticism.
It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

As a result, it may contain incomplete or even dangerously wrong information! You can help by expanding upon or correcting it. Note: Always conduct independent research and use harm reduction practices if using this substance.
Haloperidol can have serious side effects at higher dosages, such as risk of having severe extrapyramidal symptoms and muscle rigidity, which can last for hours.
Both typical and atypical antipsychotics can cause tardive dyskinesia.[5] According to one study, rates are lower with the atypicals at 3.9% as opposed to the typicals at 5.5%.[6] Switching to these atypicals is an option to minimize symptoms of tardive dyskinesia caused by other atypicals.[7]
